Re: Text Substitution and Script

That worked. Thank you.

As you may have inferred from my writing, I am at the
beginning of the learning curve. It will be helpful to
know under what circumstances can a script be executed
simply by typing

/home/> scriptname

/home/> ./scriptname (what you have suggested)

/home/> source scriptname (this has worked for me for
other simple tasks)

Once again thanks.

Kind Regards,
Venky Chakravarthy

hi,
source will not execute/lunch the script.. It only
will source/load the  setting into your environment..
What u can do is,

change your script to be executable
1)chmod 755 myscript
Execute your script
2)./myscript
